I Myinvention relates"to anew aha prov'ed hitch, and moreparticulanlyntoa' hitch i for use in connection with hay loaders.

attaching'the wagon to a hay loader; it is desirable to have thiswagon-sorennected with the loader that it can be readily disconnectedtherefrom when it has become fully loaded; At this time the attendant isusually on top of the loader, and it is, therefore',desirable -tohavenieans for operating the hitch to disconnect the wagon from .theloadeiv'operative from a position on top of 3 i the loader.

i My invention relates to a simple and improved hitch whereby a verysecure connection can-be obtained between the wagon clevis and the hayloader, and this hitch can be readily disconnected by the attendant morewagons that may vary in height from the ground and may still be used incon nection with the samehay loader.

These and other objects of my invention will be more readily understoodby reference to the accompanying drawings, in which- 7 Figure 1 is aside elevation of my improved hitch. Fig. 2 is a plan view of the same.Fig. 3 is a cross-sectional view. Fig. 4; is an end view. Figs. 5 and 6are sectional details. 7

As illustrated, I have shown a tongue 7 which is slidably mounted in thebrace-bars 8 and 9 which are secured to the hay loader in any desiredand well known manner. These brace-bars are connected by a crossbrace10. Mounted upon this cross-brace of the tongue there a supporting brace18 wi'thwwhich' the end'l'd' of the' 'dog "15 is adaptedto engage whenil'l' lp lii l lg pbsji}; tionfi f 1 Upon'the upper surface of thetdn'gue is likewise- .;provided a plate wliicli is slotted at' 20 so "as"to allow-"the ntl ofthe' dog to pass"therethrough: msa late 19 thusacts as a I guide for th dog. to' prevent' lateral movementmf thesanie.;" A* un termediate point on the said-dog a pair of laterallyextending ends of which are secured springsfif,

the ere eonopposite ends of which sprin s nected with 'th'e tonguesspring tension-is "I'na inta1ne tending-- to hold the satlon.

-Atth'e wardlv eXtending' eai 23 1 to *vvh-ich 1 nected an operatingcord 24. This cord extends rearwardly around the guide pulley 25 andthen extends upwardly into a suitable position to be operated by theattendant on top of the load. It will be readily seen that by exerting apull upon the cord 24 the dog 15 will be swung about itspivotso as tohold the curved end 16 out of engagement with the wagon clevis 17.

Pivoted beneath the tongue there is a jointed leg 26 which leg, isadapted to sup port the tongue when this leg is in vertical position. Asthe hay loader is drawn forward this supporting leg merely drags alongthe ground. When the hay loader is stopped and then backed slightly,this-supporting leg is brought to a vertical position in order tosupport the tongue. The chain '27 prevents this leg from swinging pastvertical position. The'wagon clevis 17 is vertically adjustable upon avertical bar 17, which bar V is bolted to the rearot the Wagon racli; By

' the 'clevis 17-bemade adjustable in a vertical means of thisadjustment the clevises upon different wagonscan be adjusted to thesameheight, so'that they all engage pi'operlyxvitli the dog '15. 1 Y

When it is desired todisconneetthe loader from the wagon the team isfirst backedsol that the'post;26*reaches a vertical positionathe chain2,7 preventing this'post from going beyond this position. pullsl'lPOI1',tllG cord 24 to] unlock the coupling; andthe team is thendriven forward. The post '26 being'in averticalposition, the

pole of the loader "is held atthe same height at all times,and inorderto 'couplea wagon to the loader t is merely; necessary to-back thewagon until the-couplingis made and then, when the loaderiis drawnforwarchthe' po'st 26 will trail backward. From this-it will be seenthat it is "ery importantjthat "13 can'again be inserted.'Thisadjustment is possible on account of the series'of holes 12 whichare provided inthetongue-f fhile I have illustrated one particular formof my invention, it will be understood that I do "not wish tolimitvmyself-to the exact construction shown and described.
